Cyanthillium cinereum - flower head

Cyanthillium cinereum (also known as little ironweed) is a species of perennial plants in the sunflower family. The species is native to tropical Africa and to tropical Asia (India, Indochina, Indonesia, etc.) and has become naturalized in Australia, Mesoamerica, tropical South America, the West Indies, and the US State of Florida.^{[2][3][4][5][6][7][8]}

Cyanthillium cinereum is an annual herb up to 120 cm (4 feet) tall. It produces flat=topped arrays of numerous flower heads, each with pinkish or purplish disc florets but no ray florets.^[8] The species can be confused with Emilia sonchifolia, but the flower bracts of the latter are much longer and vase-shaped.
